 DETAILED DESCRIPTION OF ILLUSTRATED EMBODIMENTS

The following description is provided in relation to several embodiments which may share common characteristics and features. It is to be understood that one or more features of any one embodiment may be combinable with one or more features of the other embodiments. In addition, any single feature or combination of features in any of the embodiments may constitute additional embodiments.

In this specification, the word “comprising” is to be understood in its “open” sense, that is, in the sense of “including”, and thus not limited to its “closed” sense, that is the sense of “consisting only of”. A corresponding meaning is to be attributed to the corresponding words “comprise”, “comprised” and “comprises” where they appear.

The term “air” will be taken to include breathable gases, for example air with supplemental oxygen.

Interconnection of Cushioning Element and Apparatus

In accordance with an embodiment of the present invention, a removable interconnectable cushioning element (also referred to as a cushion element or cushion) is provided. The cushioning element preferably includes a soft resilient foam interfacing portion for contacting a human. The cushioning element is constructed and arranged for removable interconnection with the rest of the apparatus, for example a respiratory mask.

The ability to removably connect the cushioning element enables one to replace the cushioning element should it become soiled and/or uncomfortable. It also facilitates trial of different forms of cushioning element. One form of cushioning element, for example a foam-based cushioning element, may be used as a form of “training” system to allow a person to become accustomed to the sensation of wearing and using a mask. A foam-cushion based mask may provide an initially more appealing and comfortable surface for a new patient than a gel or silicone-based cushion. The patient may subsequently switch from the foam-based cushion to a silicone or gel based cushion. In this way, the patient may be more likely to adhere to therapy because they are used to the very soft comfortable feeling of foam.

When applied to respiratory equipment, the cushioning element is adapted for connection with a mask frame. In use, an air-tight seal is formed between the cushioning element and the frame. This arrangement could be used for both nasal and full-face masks.

For example, FIG. 1 illustrates a mask 10 including a mask frame 20 and a foam-based cushioning element 30 provided to the mask frame 20. As illustrated, the foam-based cushioning element 30 provides a foam interfacing portion 32 adapted to contact the patient's face in use. In this embodiment, the foam-based cushioning element 30 is adapted for use with an existing mask (e.g., ResMed's Mirage Quattro mask), which allows the patient to switch from the foam-based cushioning element 30 to the mask's existing silicone-based cushion if desired.

Dual Foam Layers

In one form of device in accordance with an embodiment of the invention, the foam-based cushioning element has two layers, i.e., an interfacing portion and a clip portion.

In an embodiment, the interfacing portion or cushion is constructed from a soft unskinned resilient viscoelastic polyurethane foam. Such a foam is disclosed in PCT Publication Nos. WO 2008/011682, published Jan. 31, 2008, and WO 2008/070929, published Jun. 19, 2008, each of which is incorporated herein by reference in its entirety. In one form, the resilient foam may be formed by a known method such as die cutting.

FIGS. 4a to 4g show a foam-based cushioning element 230 according to an embodiment of the invention. As illustrated, the cushioning element 230 includes an interfacing portion or face-contacting portion 232 and a clip portion 234 provided to the interfacing portion 232. In this embodiment, the clip portion 234 is adapted for an interference fit with a mask frame, and the width of the clip portion 234 is narrower than the width of the interfacing portion 232 (e.g., see FIGS. 4e and 4g).

In the illustrated embodiment, both an inside surface and an outside surface of the foam interfacing portion 232 are die cut. This typically results in straight cut edges, much like a kitchen sponge. The cushion may therefore have a square cross section.

In an embodiment, the clip portion of the cushioning element may be constructed from a more rigid foam than the interfacing portion. For example, the clip portion may be formed from nitrogen blown polyethylene, or some other clean, biocompatible foam having a fine cell-structure. Alternatively, the clip portion could be made from some other polymer or rubber. In an embodiment, the clip portion is adapted to form a cushion-to-frame engagement mechanism and to form a structural support for the interfacing portion.

The two layers (i.e., the interfacing portion and the clip portion) may be adhered to one another using polyurethane hot melt glue. This arrangement provides a one piece cushioning element with an interfacing portion adapted to engage the patient's face and a clip portion adapted to interface with the mask frame.

Cushion-to-Frame Engagement Mechanisms

According to an aspect of the invention, the cushion-to-frame engagement and connection mechanism provided by the clip portion may include a channel-type engagement or rib-type engagement.

As shown in FIG. 2, the channel-type engagement includes a foam clip portion 34 that is adapted to be received within the channel 22 of a mask frame 20 with an interference fit. The foam clip portion 34 extends around the entire perimeter of the cushioning element so as to form an air-tight seal and retention with the mask frame.

As shown in FIGS. 3a to 3c, the rib-type engagement includes a foam clip portion 34 with one or more slots 38 to receive inner and/or outer ribs 23, 24 of the mask frame 20. For example, the slot to rib engagement may provide an inner frame rib engagement (see FIG. 3a), an outer frame rib engagement (see FIG. 3b), or an inner and outer frame rib engagement (see FIG. 3c). This arrangement provides a broader base of support for the sealing foam.

FIGS. 5a and 5b illustrate a foam-based cushioning element 830 including a foam interfacing portion 832 and a clip portion 834, and FIG. 5c illustrates the cushioning element 830 provided to a mask frame 20. As shown in FIGS. 5a and 5b, the clip portion 834 includes a slot 838 adapted to receive a rib of the mask frame 20. Also, providing a wider clip portion 834 allows more stiffness and structural integrity to be provided to the clip portion, making the clip portion easier to assemble to the mask frame.

When structured to form an interference fit with the mask frame, the clip portion may have the following properties: appropriate rigidity (e.g., less than that of the frame and in one form more rigid than the foam interfacing portion); non-porous; and/or low compression set (the amount of deformation expressed as a percentage of original dimensions) which a material retains after compressive stress is released (in this way, the clip portion maintains its retention force during its usage life).

Interfacing Portion Support Structure

In accordance with an embodiment of the invention, a range of different arrangements of clip portions and foam interfacing portions may be provided. For example, the width of the clip portion may match the interfacing portion, the width of the clip portion may be less than the width of the interfacing portion, or the width of the clip portion may be greater than the width of the interfacing portion.

When the width of the clip portion is less than the width of the interfacing portion, the clip portion and interfacing portion may be arranged such that (i) the outer perimeter of the clip portion and interfacing portion align (hides hardness of clip portion and provides desired freedom of movement in the interfacing portion), (ii) the inner perimeter of the clip portion and the interfacing portion align, or (iii) neither the inner or outer perimeter of the clip portion and the interfacing portion align.

Similarly, when the width of the clip portion is greater than the width of the interfacing portion, the clip portion and interfacing portion may be arranged such that (i) the outer perimeter of the clip portion and interfacing portion align, (ii) the inner perimeter of the clip portion and interfacing portion align, or (iii) neither the inner or outer perimeter of the clip portion and the interfacing portion align.

In these different configurations with different relative widths, the clip portion provides different forms of support of the interfacing portion.

When the width of the clip portion is less than the width of the interfacing portion and the outer perimeter of the clip portion aligns with the interfacing portion, the interfacing portion is more free to flex in regions not having a clip portion next to it than in regions having a clip portion adjacent to it. For example, where the interfacing portion overhangs the clip portion, that overhanging region of the interfacing portion has more freedom to move. This arrangement can be more comfortable and more able to adapt to different geometries of a person, and provide the correct vectors to seal the interfacing portion against the face.

When used as part of a respiratory mask, it may be preferable that the inner portion of the interfacing portion overhang the clip portion. In this arrangement in use, the face of the patient may engage with an unsupported inner edge of the softer interfacing portion causing it to bend and conform to the individual patient's shape.

FIG. 7a shows an elevation view detail from the frame side of the cushioning element 230 shown in FIG. 4e in a nasal bridge region. As shown in cross-section in FIG. 7b, it is apparent that the width w2 of the clip portion 234 is less than the width w1 of the interfacing portion 232 and that the outer perimeter of the clip portion 234 and the interfacing portion 232 are aligned. An advantage of this arrangement is illustrated in FIG. 7c where in use the nose is able to push the inner perimeter of the interfacing portion 232 in the direction shown by the arrow, in a cantilever manner as well as compressing.

FIG. 8 is a cross-section showing the clip portion 234 of the cushioning element 230 received within the channel 22 of a mask frame 20. It can be seen that the width of the clip portion 234 is less than that of the interfacing portion 232, and that the outer perimeter surfaces 236 and 238 respectively of the clip portion 234 and interfacing portion 232 are aligned while the respective inner perimeter surfaces 240, 242 are offset.

This arrangement is in contrast to prior art cushions (such as the Lifecare mask shown in FIGS. 6a and 6b) where the inner perimeter of the cushion C abuts the frame F, and hence it is not free to move inwardly and can only compress.

In one form, a mask system may be provided that includes at least two different forms of cushioning element chosen from the set of foam-based cushion, silicone-based cushion, and gel-based cushion.

While the invention has been described in connection with what are presently considered to be the most practical and preferred embodiments, it is to be understood that the invention is not to be limited to the disclosed embodiments, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention. Also, the various embodiments described above may be implemented in conjunction with other embodiments, e.g., aspects of one embodiment may be combined with aspects of another embodiment to realize yet other embodiments. Further, each independent feature or component of any given assembly may constitute an additional embodiment. In addition, while the invention has particular application to patients who suffer from OSA, it is to be appreciated that patients who suffer from other illnesses (e.g., congestive heart failure, diabetes, morbid obesity, stroke, bariatric surgery, etc.) can derive benefit from the above teachings. Moreover, the above teachings have applicability with patients and non-patients alike in non-medical applications.
